If you do npm help install you will see that:

  o   npm install (in package directory, no arguments):

      Install the dependencies in the local node_modules folder.

      In global mode (ie, with -g or --global appended  to  the  com-
      mand), it installs the current package context (ie, the current
      working directory) as a global package.
